Avatar cropping errors

I recently upgraded to 1.5.6 and now the avatar upload isn’t working.
I can upload the pictures via the uploader and see them in wp-content/uploads/(user-id), but the cropper and previewer don’t work. I tried on Chrome and Internet Explorer.
It seems like the script the can’t find the pictures even though it uploaded them fine.
I tried turning off wp-cache with no results, and also tried deactivating plug-ins.

Have checked and multichecked wp.config, have checked htaccess, have totally replaced all wp-include and wp-admin files and root folder php files to original, have set folder permissions up to 777 on wp.content and set to recurse, have tried every theme, including default BP…. avatars go blocky after a while, and when you try to upload any avatar via BP Change Avatar, it uploads fine but then shows a block size of about 80 pixels by 80 pixels of the image uploaded’s top left hand corner only..

Any ideas on ending this nightmare… and no not gravatar. Also I found that when i upload via admin dashboard using say plugin like Local Avatar, it works fine… Yep, removed just about all plugins, including Quick Cache… totally lost on this

sounds like you folks aren’t seeing the crop tool handles that corner thing is how it starts out but you should be able to resize the square on the full thumbnail. i don’t really know more then that sorry.
